Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for greening a non-soil surface such as a concrete floor surface on a rooftop of a building.

[0002]

In recent years, from the viewpoint of protecting the natural environment, it is also called roof greening, and greening of non-soil surfaces such as concrete floor surfaces of building roofs is strongly required. Has reached. However, since it is extremely difficult to implant general soil on a non-soil surface including such a concrete floor surface, the present invention provides appropriate soil water retention and drainage properties and various soil fungi. An object of the present invention is to provide a greening method for constructing and forming a lightweight planting ground capable of curing natural soil microorganisms containing, and planting on the planting ground.

[Means for Solving the Problems]

The structure of the present invention for achieving the above object will be described with reference to an embodiment. Firstly, the greening method according to the present invention is, firstly, a cedar material which is divided into strips and from which lignin is removed. The present invention is characterized in that an aggregate of chips 1 is deposited on a non-soil surface 4 such as a concrete floor surface on a rooftop of a building to construct a planting ground 3, and the planting ground 3 is planted. .

Secondly, the inside of the shape-retaining frame 2 made of a basket, bag, etc. having water permeability and air permeability, which is an aggregate of cedar chips 1 divided into strips and having lignin removed. To form a ground 3 for planting, and lay one or a plurality of the ground 3 for planting on a non-soil surface 4 such as a concrete floor surface on the roof of the building. It is characterized by planting on the ground 3.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings.

EXAMPLE FIG. 1 is a perspective view of a planting ground used in the greening method of the present invention, and FIG. 2 is a longitudinal sectional view illustrating a state in which the planting ground is laid.

[0007] An aggregate of cedar wood chips 1 that have been cut into strips and from which lignin has been removed is a basket formed of a zinc aluminum alloy plated iron wire or the like having water permeability and air permeability, or is a rot resistant one. It is filled and housed inside a shape-retaining frame 2 such as a mattress formed of a bag formed of a synthetic resin net such as polypropylene, polyethylene, nylon, etc. to form a planting ground 3.

The strip of the cedar wood chip 1 is not particularly limited in its specific shape, and may be a granular body having an indefinite shape or a cylindrical body or a prismatic body depending on the convenience of the manufacturing process. However, the outer diameter is preferably about 5 to 10 mm, and the lignin is removed. The lignin removal processing can be performed by using a known means.

An aggregate of cedar chips 1 as described above is
A planting ground 3 is obtained by filling and storing it inside a shape-retaining frame 2 composed of a basket, a bag, and the like having water permeability and air permeability. It is also possible to polymerize and use both the basket and the bag.

If necessary, it is possible to mix plant seeds in the aggregate of the planting ground 3 and the cedar wood chips 1.

One or a plurality of the planting grounds 3 as described above are laid in parallel on the non-soil surface 4. Then, desired plants are planted on the planting ground 3. Here, an auxiliary water supply device can be attached if necessary.

[0012] The cedar wood has a very clear arrangement of the conduits that make up the interior thereof, and even if lignin is removed, these conduits do not collapse, and they retain their desired shape indefinitely. It is excellent in durability, has little variation in physical properties, is extremely widespread in nature, and exists in large quantities, and is very easily available.

The cedar wood chip 1 from which lignin has been removed is composed of a myriad of fine, cellulosic, capillary-like conduits, and since water can permeate throughout the interior of the cedar-like conduits, The water easily invades, the water once contained is not easily separated, and the excess water is drained to the outside through the gap of the aggregate.

Similarly, the microorganisms inhabiting the water also invade and settle inside the cedar wood chip 1.
Anaerobic bacteria colonize the inside of the and aerobic bacteria segregate and settle on the surface. This segregation forms a colony, which at the same time promotes the survival of small animals including plants and microorganisms, forming a kind of microcosm (artificial ecosystem) that maintains the habitat such as temperature, humidity, nutrients and food. It is possible to expect a natural purifying action, which is very preferable.

The aggregate of the cedar wood chips 1 is used as a non-soil surface 4
When installed above, rainwater is kept in the cedar material chip 1 having a high water-retaining capacity, and an environment suitable for planting can be formed regardless of the non-soil surface 4.

Under such an environment, when seeds of plants are mixed in the aggregate of cedar wood chips 1, the seeds germinate, and when plants are planted, the plants grow. It is possible to cover the surface of the planting ground 3 and achieve greening.

In the present embodiment, an aggregate of cedar wood chips 1 which were cut into strips and from which lignin had been removed was molded with a zinc aluminum alloy plated iron wire or the like having water permeability and air permeability. The ground 3 for planting was made by filling and storing it inside a shape-retaining frame 2 made of a bag or the like formed of a basket or a net made of synthetic resin such as polypropylene, polyethylene, nylon, etc., which are resistant to decay. Without filling the shape retention frame 2 with the aggregate of the wood chips 1, the aggregate of the cedar wood chips 1 is directly deposited on the non-soil surface 4 to construct the planting ground 3, and It is also possible to plant on the ground 3 for planting.

[0018]

As described above, according to the present invention, an aggregate of cedar wood chips 1 divided into strips and having lignin removed can impart appropriate water retention and drainage properties, It is possible to cure natural soil microorganisms including various kinds of soil fungi, to easily construct and form a lightweight planting ground on a non-soil surface, and to achieve remarkably excellent greening.
